Thread: Dot 5

I vaguely recall there were limitations on its use, perhaps with regards to the typre of "rubber" used in the system.

How is the pedal feel? It's supposed to be a bit more squishy, but I've never tried it.

Yep, silicon fluid is a lot more compressible than a polyglycol ether fluid but it wouldn't be a problem in a clutch.

i thought about using silicon fluid in the morrie minor but the phenomenal cost of the fluid put me off. I could replace most of the braking system for the cost of a few litres of the fluid. Has the cost come down?

I have found the best and easiest place to buy it is at Harley Davidson outlets as they market it under their own brand. Comes in a 13 fluid ounce bottle and price is pretty good at the moment due to dollar being high. It's not real cheap but I didn't have to take the deed for the house in to buy it. It was about $12, reasonable when you consider it costs about $60 to fill the fuel tank nowadays, and thats gone in a week or less.
Clutch system only used about 1/4 - 1/3 of a bottle. Good thing with it is it doesn't wreck paint and doesn't attract water.

Cheers, Mick

Not sure about that, but it cannot be used in ABS systems.

I asked my supplier some years ago why Silicone fluid was not recommended for ABS systems. He said no one will spend the $50000 to get it certified for ABS, otherwise it will be ok. I have been using it since 1988 and is still in use. Its in my D1 too.
